Abstract
Here, we describe a new species of Cyrtodactylus Gray from East Java (Dampit, Malang), Indonesia that belongs to the C. marmoratus species group. It is a medium-sized (SVL) species with adult males reaching 65.9 mm in males, 64.3 mm in females; characterized by dorsal tubercle absent on brachium, 17–18 dorsal tubercle rows, 38–40 rows of smooth ventrals, precloacal depression present in a deep groove, 15–17 precloacal pores in an inverse Y shape, 7–12 femoral pores, 3–5 poreless femoral scale separated precloacal and femoral pores in males, 2 pairs of post caudal tubercles, second post mentals separated by 5–7 scales, abrupt transition between rows of large and small postfemoral and ventral femoral scales, and no enlarged subcaudals. The new species is genetically divergent from the other Javan congeners of the C. marmoratus complex with genetic divergences (p-distances) ranging from 15.1–24.3% for the mitochondrial ND2 gene. This description brings the number of nominal species of bent-toed gecko in Java to six.

 Diagnosis. The new species is a distinct evolutionary lineage closely related to C. belanegara, C. marmoratus, and C. semiadii. It can be differentiated from other congeners by the following combination of characters: known maximum SVL  65.9  mm  in  males,  64.3  mm  in  females; two  pairs  of  post  caudal  tubercles; second  post  mentals separated by 5–7 scales; 17–18 dorsal tubercle rows; 30–35 paravertebral tubercles; 38–40 ventral smooth scales across  midbody;  precloacal  depression,  precloacal  and  femoral  pores  present  in  male;  precloacal  depression  in  a deep grooved form; 15–17 precloacal pores arranged in an inverted Y; 7–12 femoral pores; 3–5 poreless femoral scales separated from precloacal and femoral pores; abrupt transition between rows of large and small postfemoral and ventral femoral scales; absence of enlarged subcaudals.

Etymology. The specific epithet is a noun in apposition, “mendol.” Mendol (Figure 8) is a traditional food typical of Malang (East Java) and its surrounding areas, known for its delicious taste and unique history. This dish is believed to be inspired by the popular Dutch food, mashed potato fritters. During the colonial era, Malang was one of areas where the Dutch resided. The term "mendol" means ball, which describes the method of forming the food into a ball shape. This dish is made from tempeh that has undergone further fermentation. The tempeh (fermented soybean cake) is crushed and mixed with spices such as garlic, coriander, galangal, lime leaves, and chili. The tempeh dough is then shaped into an oval form and fried until golden brown. Mendol has a savory taste with a hint of spiciness and a texture that is crispy on the outside but soft on the inside. It is typically served as a side dish for meals such as rawon, lodeh, and pecel.
